WINDOW BRACKET.

Application filed April 7, 1925. Serial No. 21,334.

This invention relates to an improved adjustable bracket for windows, and it has particular reference to a bracket which is constructed to permit it to be connected to the sill in one instance for inside use, and with the guide beads for the sash for outside use.

The invention has particular reference to an adjustable bracket which is especially, but not necessarily, designed for supporting a shelf, such as may be used as a rest for a flower box, or the like.

The novel details serving to render the device exceedingly advantageous will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this application, and in which. like numerals are employed to designate like parts throughoutthe same:

Figure 1 1s a side view in section and elevation showing an adjustable window bracket constructed in accordance with the present invention, and indicating the manner in which one end of the shelf forming board is rested thereon.

Figure 2 is a front elevation of the bracket showing portions of the window structure.

Figure 3 is a detail perspective view of the inner end of the anchoring member adapted for detachable connection with the window. 7

Figure 4 is a fragmentary sectional view showing the anchoring member in top plan, and the 'manner in which it is associated with one of the guide beads.

Referring to the drawing in detail, it will be seen that the letter A designates a w1n dow sill, B designates the apron depending therefrom, and 0- represents the sub-sill. These details are seen on the insi-deof a window structure as viewed from the interior of the room.

The improved bracket comprises in the main, a longitudinally extensible supporting arm comprising an outer tubular section 1 which 1s rectangular in cross sectlon, the same being rovided at its outer end with an upturned stop 2. The shelf board 3 rests on this section, and bears against the stop. Slidable in the section 1 is a flat strip 4 held in various adjusted positions bythe set screw 5. The strip 4 has its inner end down turned as indicated at 6 and the extremity of the downturned portion is formed with angularly disposed serrations forming teeth 7 to bite into the outer vertical edge of the window sill as indicated in Figure 1. Secured to this strip 4 on one edge is a lateral hook 8, the purpose of which will be hereinafter described. The shank 9 of this hook is fixedly secured to the edge of the strip in any appropriate manner, the hook terminating preferably in spaced relation from the down bent end 6.

Disposed directly beneath the tubular section 1 is a correspondingly shaped inclined member 10 having its bent end 11 secured to the under side of the tube 1, as shown more plainly in Figure 1. A flat leg 12 is slidable in the member 10, and is held in adjusted positions by the set screw 13. It will be observed that this leg 12 is provided with a cross piece or head 14 on its lower end adapted to rest against the wall D. It is yet to be pointed out that a brace 15 is interposed between the parts 10 and 1.

Assuming that it is desired to support the shelf 3 within the room, it is of course. obvious that one of the improved brackets must be attached at each side of the window frame, to support the opposite ends of the shelf. In this instance the teeth 7 are embedded in the window sill as indicated in Figure 1, and the parts 1, 10 and 15 are adjusted as a unit toward or from the sill to osition the shelf in the desired place. The eg 12 is adjusted downwardly so that the cross piece 14 is brought to bear against the wall. Thus, the shelf will be rigidly su ported in lace. If it is desired to place tide shelf on t e exterior of the house, the adjustments of the brackets are made in exactly the same way described, but at this time the hooks 8 are simply engaged with the outer beads E as indicated in Figure 4, the teeth 7 being ineffective at this time.

' It is thought that by considering the description .in connection with the drawings, persons familiar with devices of this class will be able to obtain a clear understanding of the same, and that the advantages derived from such a structure will be clearly apparent. For this reason a more lengthy description is deemed unnecesary.

Although the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described the invention, what I claim as new is:

A window bracket comprising a horizontal lon itudinally extensible supporting arm for a s lelf, said arm being made up of telescopically connected sections, the outer end of the outer one of which is formed with a stop, the inner end of the inner section being bent downwardly, and the extremity of the downturned end being formed with angular serrations providing teeth, a downwardly inclined tubular member fastened to said outer section, a brace interposed between said tubular member and outer section, an adjustable leg slidable in said tubular member and provided on its free lower end with a cross piece adapted to bear against a supporting surface.

In testimony whereof I aflix my signature.

WILLIAM H. JOHNSON.
